  1. 1. The__________ is the standard unit of measure for power.
  2. 3. - Gravity is a force caused when the mass of physical bodies attract each other. On Earth gravity pulls at objects with an acceleration of 9.8 m/s2.
  3. 6. - A scalar is a measurement that only measures the magnitude. Unlike a vector, a scalar does not have direction.
  4. 7. energy - Potential energy is the energy stored by an object due to its state or position. It is measured in joules.
  5. 10. - Acceleration is the measurement of the change in an object's velocity. It is equal to the change in velocity over the change in time. Acceleration is a vector.
  6. 11. - A collision in physics occurs when any two objects bump into each other.
  7. 13. A vector is a quantity that has both a magnitude and a direction.
  8. 15. - Force is the measurement of a push or pull on an object. Force is a vector measured in newtons.
  9. 18. - An impulse is a change in momentum.
  10. 21. - Friction is the resistance of motion when one object rubs against another. It is a force and is measured in newtons.
  11. 22. - Momentum is a measurement of mass in motion. Momentum is equal to the mass times the velocity of an object. It is a vector measured in newton-seconds.
  12. 23. - In physics, displacement refers to an object's overall change in position. It is a vector quantity.
  13. 25. ______________ is the force of gravity on an object. In physics, weight is measured in newtons.
  14. 26. __________is a vector quantity. The magnitude of__________ is the object's speed.

  1. 2. The third law of motion states that for every action there is an equal and opposite reaction.
  2. 4. - The pascal is the standard unit of measure for pressure.
  3. 5. Velocity is the rate of change in an object's position.
  4. 8. law of motion - The second law of motion states that the greater the mass of an object, the more force it will take to accelerate the object.
  5. 9. - Pressure is the force over a given area. Pressure is measured in pascals.
  6. 12. - Power is a measurement of the rate at which energy is used. Power is calculated by dividing work over time. The standard unit for power is the watt.
  7. 14. - The joule is the standard unit of measure for energy and work.
  8. 15. law of motion - The first law of motion states that any object in motion will continue to move in the same direction and speed unless external forces act on it.
  9. 16. energy - Kinetic energy is the energy an object has due to its motion. It is a scalar quantity calculated using the formula KE = ½ * m * v2, where m = mass and v = velocity.
  10. 17. - Energy is the ability to do work. The standard unit of measure for energy is the joule.
  11. 19. is the measurement of how fast on object moves relative to a reference point. It is a scalar quantity measured by distance over time.
  12. 20. machine - A simple machine is a basic mechanical device for applying a force and doing work. Some examples of simple machines include the lever, pulley, inclined plane, wedge, and screw.
  13. 22. - Mass is a measurement of how much matter is in an object. It is usually measured in kilograms.
  14. 24. - The newton is the standard unit of measure for force.
